Can a new fuel filter do this?? Wow!!!

When you change the filter, do yourself (or the next owner) a favor by writing the date on it.

Shayne,

Thanks for this thread! I had been experiencing the same issues you described so I ordered a new filter from our host and swapped it out today. WOW, what a huge improvement.

John,

That's exactly what happened with mine today. I'd read a few threads here about chaning the filter and saw where several mentioned getting fuel all over the place once they disconnected the fuel lines.

When I disconnected ine, there wasn't a lot of fuel :flowing" out...it was more of a "dribble".

I still can't believe how much better she runs again. The old filter had about 15K miles on it since May, 2002. You can bet THAT won't happen again!

all post about 0ctan confused me. I am using 91 octan on all german cars and still using it on this car now. But several people told that on this old 88 engine, 87octan is ok. No need for 91octan. I didn't believe it at first but heard many times and now this thread confused me. What is it about the detonation story?
Can anyone help me to clear this out?

The newer cars like higher octane fuel, but older ones like mine are quite happy with 87. Check your owner's manual for Porsche's recommendation.

An '87 requires high octane fuel. My '88 owner's manual said it required high octane so that's what I used.

Yes as Masraum said, READ THE F@@@@ OWNER"S MANUAL!

Beep Beep, you are giving bad advice in this case 911 engines (I totally agree with Nick and Steve). False economy putting in cheaper gas for your expensive engine. Your advice is completely correct if you are talking Japanese water-cooled engines with or w/o knock sensors (however, one will not get better performance claimed by Honda if you put lower octane gas even though your engine will not be harmed).

Indigowhale, you shouldn't be messing with any Motronic german engine without the proper tools (LM-1 A/F mixture adjustment device sold by Pelican host) and by ear, taste, or feel (all of which I suspect are not calibrated).
